1. A high density network arrangement for managing an integrated secured multiple networks arrangement, comprising:
a plurality of network interfaces, wherein each network interface of said plurality of network interfaces is configured for coupling with a network arrangement;
a dual bypass module for protecting data traffic flowing through said plurality of network interfaces while providing network access by: tapping, at a network tap, said data traffic and sending tapped data traffic to a monitoring system on a path between the network tap and the monitoring system; testing a condition of the monitoring system and the path between the network tap and the monitoring system by sending one or more sets of sequential heartbeat packets to the monitoring system; and bypassing the monitoring system in response to detecting a negative condition of the monitoring system or the path between the network tap and the monitoring system based on a negative response or lack of response from the monitoring system to the one or more sets of sequential heartbeat packets; and
a logic module for managing policies for setting a security mode between said high density network arrangement and the monitoring system and for modifying a heartbeat packet of the one or more sets of sequential heartbeat packets sent to the monitoring system for a diagnostic test by adding network information, to the heartbeat packet, about data traffic flowing through said high density network, wherein the network information comprises an alarm status based on a utilization rate of the high density network arrangement.
